Christina Hawthorne (Jada Pinkett-Smith) is the kind of nurse you want on your side when you or someone you love is in the hospital. She is the kind of nurse who fights for her patients and doesn't let them slip through the cracks. When necessary, she takes on doctors and administrators who are overworked, distracted, or just unable to see the human being behind the hospital chart. Whether showing humanity to a homeless woman, trying to talk a suicidal cancer patient off a ledge, or exposing a doctor's near-fatal error, Hawthorne will do everything in her power to help her patients. Hawthorne is recently widowed — her husband died one year ago after a battle with cancer, leaving her to raise a smart, rebellious teenage daughter on her own. Hawthorne is still coming to terms with losing her husband, finding a way to balance her career with her equally important role as a single parent, and finding the time to take care of someone who always seems to fall through the cracks — herself.
